High-voltage DC relays can be widely used in electric high-voltage fields such as electric vehicles, hybrid electric vehicles HEV,
fuel cell vehicles, photovoltaic power generation, wind power generation, cloud server power supply,
battery charge and discharge systems, DC voltage power control and heavy machinery.
1. Power supply/motor control, circuit insulation, circuit protection and safety devices for industrial machinery.
2. Used for car battery power distribution and backup.
3. Used for inverter power control.
4. Used for electric vehicle charging piles.
5. Used in solar power generation equipment.
product characteristics:
1. Can control high current and high voltage
Ceramic brazing sealing technology: The contact chamber is filled with inert gas, combined with magnetic blowout and arc
extinguishing, so that the product can carry up to 10 times of overload current.
2. Compact structure and low working noise
The shape can be made small by using an arc-free gap structure that does not allow the arc to leak.
Thanks to the sealing of the contacts in the inert gas compartment, efficient and safe shut-off is ensured even if the
contact gap is small.
The working noise is small, as is the case when switching large currents.
3. Good security
The contact is sealed in a sealed ceramic vacuum chamber without the risk of arc leakage and explosion-proof design,
thus ensuring good safety of the product.
4. High contact reliability
The contact unit is sealed in an inert gas, so the contact resistance remains stable regardless of the environment.
5. There is no special requirement for the installation method. The movable part is light in weight, and the reaction force is large
. The product is affected by gravity. There are two installation methods, side and bottom. There is no special requirement for
the installation position.
Functional features:
1, comply with RoHS requirements
2, the product contact part sealed, in line with IP67 requirements
3, small size, light weight, safe and reliable
4, strong anti-magnetic interference ability, explosion-proof
5, the contact is sealed in the ceramic chamber, and is filled with gas with high cooling arc ability
6, permanent magnet blow arc out, high voltage DC cut off, contact end and coil connection end have polarity requirements
